3.4 Inch Square Display 540×540 RGB

HONGJIA 3.4 Inch Square Display 540×540 RGB is developed for electronic manufacturers requiring a square-format display module with reliable performance and flexible connection options.

The HJ34001-01FPC-A1 adopts a 3.4-inch IPS TFT LCD with a symmetrical 540(RGB)×540 pixel resolution, providing an equal horizontal and vertical display area for graphical interfaces, control panels, and information visualization. Equipped with the JD9261T driver IC, this module supports RGB 16-bit, 18-bit, and 24-bit input signals through a 45-pin standard plug connection.

With IPS full viewing performance, 450 cd/m² brightness, 16M display colors, and a wide operating temperature range from -30°C to +80°C, this square display module provides a reliable solution for industrial equipment, smart devices, and embedded electronic products.

Square Screen Format for Balanced Interface Layouts

The HONGJIA 3.4 Inch Square Display 540×540 RGB adopts a square display structure with equal horizontal and vertical dimensions.

The 540×540 pixel resolution provides a balanced visual area, allowing designers to create symmetrical user interfaces, graphical controls, circular menus, dashboards, and smart device displays.

Compared with traditional rectangular LCD modules, the square format provides more flexibility for products where display proportion is an important part of the overall design.

RGB Interface Supports Multiple Color Configurations

The display module supports RGB 16-bit, 18-bit, and 24-bit interfaces, allowing engineers to select different color depth configurations according to system requirements.

The RGB interface provides a practical connection method for embedded systems, while the 45-pin standard plug connection helps simplify hardware integration and product development.

IPS Panel Provides Consistent Viewing Performance

The module uses IPS panel technology with ALL O’CLOCK viewing direction, maintaining stable image quality and color performance from different viewing angles.

With a transmissive normally black display mode and 16M display colors, the screen delivers smooth image transitions and clear visual output for various electronic interfaces.

JD9261T Driver IC Ensures Stable Display Control

The HONGJIA 3.4 Inch Square Display 540×540 RGB integrates the JD9261T driver IC for reliable display control and RGB signal processing.

The driver solution supports stable operation in embedded applications and helps manufacturers develop products requiring continuous display performance.

Designed for Wide Temperature Operating Conditions

This square display module is designed for applications where environmental conditions may vary.

The operating temperature range reaches -30°C to +80°C, while the storage temperature range supports -30°C to +85°C.

This wide temperature capability makes the display suitable for industrial equipment, medical devices, and smart control systems used in demanding environments.

Compact Structure for Embedded Product Integration

The module combines a large active display area with a compact mechanical structure.

Key dimensions include: Active Area: 60.59(H)×60.59(W) mm Outline Size: 63.22(H)×67.13(W)×2.19(T) mm

The slim structure allows integration into space-limited electronic products while maintaining sufficient display area for user interfaces and graphical content.
